Witnesses Afiorneys FREIDRICK H. SMITH, OF PITTSBURG, KANSAS LUBRICATEDHUB-PLATE.

To all whom it may concern Be it known that I, FREnRIoK H. SMI'rH,

a citizen of the United States, residing at Pittsburg, in the county ofCrawford and State of Kansas, have invented a new and useful LubricatedHub-Plate, of which the following is a specification.

One object of the present invention is to.

provide novel means for securing a'hub plate in the wheel of alocomotive engine, in a boxingor like structure, to prevent lateral lay.

Another object of the invention isto provide novel means for feeding alubricant through the hub plate.

Nith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination'andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in' the preciseembodiment of invention here disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings :Figure 1 shows the invention in transverse section;Fig. 2 is an elevation of the hub plate; Fig. 3 1s a perspective of oneof the constituent members of the hub plate; Fig. 4 is a fragmentalsec.- tion on the line M of Fig. 2; Fig. 5 is a fragmental section onthe line 5-5 of Fig. 2; and Fig. 6 is a perspective showing the plateassembled with a boxing.

In the drawings, the numeral 1 indicates the wheel of a locomotiveengine, although at this point it may be stated that the invention maybe applied to vehicles other than a locomotive. The wheel 1 is providedin its inner face with anannular recess 2, receiving an annular hubplate which is denoted generally by the numeral 3, the hub plate beingengageable by the bearing (not shown), as is common and Well understoodin the art. The hub plate 3 is provided with. a reduced inner end 4which fits in ChGflII'f nular recess 2. The hub plate may be variouslyfashioned, but in the present instance it is shown as comprising a pairof sections denoted by the numerals 5 and 6.- The sections 5 and 6 areprovided along their meet ing edges with interengaging elements whichprevent relative transverse movement between the sections. In thepresent instance, the interengaging elements above re ferred to comprisea groove 7 formed in the Specification of Letters Patent.

section 5 and a' tongue 8 formed in the section 6 and adapted to enterthe groove 7. The tongue 8 and the groove 7 are located slightly to oneside of the vertical central plane of the hub plate. I v

Resilient means is provided for holding the sections 5 and 6 of the hubplate 3together, and for holding the sections assem bled with the hub ofthe wheel 1. To this end, the reduced portion 4 of the hub plate 3 isprovided with av circumscribing groove 9 upon its exterior, there beinga similar groove 10 in the hub 14 of the wheel 1. A

liner ring 11 fits in the groove 9 and bears against one wall of therecess 2 in the wheel 1, there being a ring 12 in the groove 10, the

last specified ring bearing against the inner periphery of the portion 1of the hub plate 3. The rings' 12 and 11 are preferably resilient.

In order to prevent rotatory movement between the hubplate 3 and thewheel 1, the hub plate is provided with a plurality of projecting dowelpins 15 which are received in recesses 16 in the wheel. The hub plate 3-is maintained in engagement with the hearing, to prevent lateral play ofthe driving wheel, by the action of a lubricant which is initiallycontained in a plurality of chambers 17 formed in the hub plate 3. Aplurality of ducts 18 lead from each of the chambers 17 through'the hubplate, and of these ducts '18 there may be any number. In

each of the chambers 17 a cap 19 fits closely, each cap being providedwith a projecting boss 20, adapted to engage the base of the recess 2 inthe wheel 1. Each cap is ,provided in its periphery with an annulargroove 21, in which a ring 22 fits closely, the ring being resilient, soas to bear against the side wall of the chamber 17.

The interlocking engagement between the tongues 8 and the grooves 7serves to prevent the sections 5 and 6 of the hub plate 3 .from havingrelative transverse movement. The sections 5 and 6 are held together,furwill be understood readily, the rings 11 and 12 serve to preventaleakage of the lubricant, and the same observation holds true withrespect to the ring 22 which is assembled with the cap 19.- The-bosses20 of the caps 19 are engageable by the face of the recess 2 in thewheel 1, thereby to advance'the caps 19 in the chamber 17 and to forcethe lubricant through the ducts 18.

It is obvious, as shown inFig. 6, that the plate 3 may be assembled withaboxing 23 tomaintaina lateral support tor-the wheel, it belng withinthe scope of the invention that the plate 3 shall work against thehub ofthe wheel or against the face .o'f the ,box-,

cap and bearing against the wall 0 ing. The plate 3 maybe of one piececonstruction, instead of the sectional construe tion which is shown.

Having thus described the invention,

what is claimed is LIn a device of the class described, a hub platehaving a lubricant-receiving opens-1 ing t erethrough; a cap mounted toslide in theopening; and a ring surroundin the the recess; the platehaving a lubricant receiving opening extending through-the platetransversely, the opening being independent of said means; and a capshdable in the opening and adapted to engage the base or the recess.

3. In a device of the class described,asup- "porting member having anannular recess; a plate fittin in the recess; means for retamingl the pate against rotation in the re cess; t e plate havin a lubricantreceiving chamber and there eing a reduced duct communicating with thechamber and extended through the plate transversely, the chamber and theduct being independent of said means; and a cap slidable in the charmher and engaging the base of the recess.

' In testimony that I claim the foregoing as my own, I have heretoaffixed my s1gna ture in the presence of twowitlisses. FREDRICK H.SMITH.
